# logger- Global

The logger API provides inbound email actions that append messages to the email log.

It provides methods that add information, warning, and error messages. The added message has its source set to `email.<Sys ID of incoming email>`.

      createInc(grUser.sys_id);
    } else {
        logger.logWarning("Sender: " + email.from + " " + "found but no userID found, please take necessary actions"); //Append warning message to the email log.
        createInc(grUser.sys_id);
